Pitched roofs

Waterproofing of pitched tin roofs

Renovation of pitched and arched (hangar-type) tin roofs using liquid waterproofing membranes is one of the smartest solutions when the tin is still mechanically sound but is starting to "wear out". It is not just painting, but creating a new, elastic layer.

That's why this technology is becoming so popular now.

Why is liquid waterproofing superior to regular paint?

Many people make the mistake of simply repainting the sheet metal. Paint provides color, but it lacks the elasticity and thickness needed for sealing.

Seamless coating:

Waterproofing covers the roof with a seamless "cocoon." There are no seams, which is where leaks usually start.

Filling minor defects:

The liquid membrane fills micro-cracks, corrosion-damaged areas and leaking rivets or screws.

Thermal movement:

A metal roof expands significantly in the summer and contracts in the winter. Ordinary paint cracks, and polymer waterproofing (such as polyurethane or silicone) moves with the metal.

Hangar waterproofing (Curved and oval roofs)

Hangars (especially older metal ones) have a specific problem – seams and joints. Due to their shape, traditional coatings (e.g. bitumen) often do not adhere well or look unaesthetic.

Complex shapes:

Liquid waterproofing is sprayed or applied, so it fits perfectly around oval shapes, where the overlaps of the sheets are the weakest point.

Vibration damping:

Hangars often “walk” due to wind. The liquid membrane acts as a shock absorber, preventing the joints from loosening.

Weight:

It is a lightweight coating that does not burden the hangar structure (unlike an additional layer of tin or heavy bitumen coating).

If the roof is "still alive", but occasional drops are annoying:


        01
Local sealing:
Special reinforcement tapes are used at the seams and bolts together with a liquid membrane.
02
Anti-corrosion preparation:
First, rusting is stopped, then a primer is applied, and finally a waterproofing layer.
03
Result:
You get the features of a new roof for 30-50% less than it would cost to completely remove the sheet metal and replace it with a new one.
